Beam correspondence

Abstract

A User Equipment (UE) configured to control lengths of one or more monitoring cycles of the UE based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE. The monitoring cycle is used to select a beam for transmission by the UE. The DRX cycle is used by the UE during RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions.

         5 . The UE according to  claim 1  wherein the controlling of the lengths of the one or more monitoring cycles is configured to conserve power of the UE. 
     
     
         6 . The UE according to  claim 1  wherein the range of the DRX cycle comprises at least one of: a short cycle, a long cycle. 
     
     
         7 . The UE according to  claim 1  wherein the beam correspondence conditions are determined such that shorter DRX cycles have a higher level of accuracy for the beam correspondence requirements compared to the longer DRX cycles. 
     
     
         8 . The UE according to  claim 1  wherein the beam correspondence conditions are determined such that shorter DRX cycle lengths have a higher level of UE transmit power compared to the longer DRX cycle lengths. 
     
     
         9 . A method comprising:
 controlling lengths of one or more monitoring cycles of the UE based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE, wherein the monitoring cycle is used to select a beam for transmission by the UE; and   wherein, the DRX cycle is used by the UE during RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions.   
     
     
         10 . The method according to  claim 9  wherein the power conditions are indicative of the available transmission power for the UE.
